CISTERNHVALVE FOR`WATER=CLOSETS.

SPECIFICATION' forming part of Letters Patent No'. 654,364, dated July 24, 19010.

Application filed August 30, 1899.' Serial No. 729,005. (No model.)

proved Uistern-Valve for Water-Closets, of. which the followingis a full, clear, and exact description.

My invention relates to an improvement in.

cistern-valves for water-closets designed to prevent their leakiu g and the consequent waste of water.

My invention comprises the novel features hereinafter described and claimed.

Reference is to be had to theaccompanying drawings', forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure l is a top or plan view of lny device in position in a cistern. Fig. 2 is a sectional elevation upon the line 2 2of Fig. l. Fig. 3 is a sectional elevation taken at right angles to that of Fig. 2; and Figse, 5, and 6 are sectional plans taken, respectively, upon the lines 4 4, 5 5, and 6 6 of Fig. 3.

It is a common occurrence with ordinary cistern-valvcs for water-closets that they will leak more or less, and consequently permita large quantityof water to flow through them which serves no good purpose. In cases where water is supplied by meter andthe water charges are proportioned to` the amount of water consumed a very small leakage of this sort will result in largely increasing the water-bill.

The object of my invention is to provide a` valve for waterclosets which shall absolutely;

prevent leakage and which will therefore stop the above-mentioned waste of water.

In the drawings the oisteru A may be of any suitable orusual form and will of course be provided with the ordinary float and Valve for keeping the same iilled with water. This iloat and valve forming no part of my present invention has not been herein shown...

Extending upward through the bottom of the cistern is apipe or tube B, which is provided with a flange b, adapted to engage the upper surface ot' the cistern-bottom, and the lower portion B of said tube, which projects below the cistern-bottom, is threaded and provided with aclamping-nut C, by means of which a tight joint may be maintained about the tube.

.To further insure ai tight joint, a packing- Washer b may be placed beneath the Hange b. The tube B extends a short distance above the normal water-level of the tank or cistern, and Within the tube is a vertical partition D,

which divides thetube into two parts. The

`lower portion ofthe partition D is connected tube'B. Above the upper end of the partition D is a transversely-extending partition G, which extends over and covers the upper end of that halt E of the tube which is connected with the inletopening e, said half constituting the suction-leg ot' a siphon when the device is in operation. This partition G is at a sufficient distance above the top of the partition D to allow ample opening for the water to flow over thetopot' thepartition D when the device is in operation;

A ball H is provided, which is otsuch size and material as to securely close the upper end ofthe tube when the same is resting thereon, as shown in Fig. 2; This ball is preferably. of rubber and is, hollow, so asto be very light and easily raised from its seat when the device is to be put into operation.

Surrounding the tube B is a cup I, which has a hole I in its bottom of such size as to This cupnormally will be down about the tube in the position shown in Fig. 3, the water in such case entering through the slight space ybetween the edgesof'the opening I andthe `sides of the tube and filling the cup with water. `The cup is providedwith two. bails J at'its upper end, which prevent the` possibility ot' the ball H escaping from the cup. The cup is suspended from a lever K by means of said bails, the lever being pivoted upon the upper end of an arm K', mounted upon the tan k, and

being operated by means of a chain or cord K2 in the usual manner. When they chain K2 is pulled, the cup I will be raised, carrying with it the Water therein. This Water when it reaches the ball II will float the same off of the end of the tube B, and the water in the cup will then be quickly discharged into the upper open end of said tube. This water as it pours into the tube strikes the partition G, which preferably is sloped after the manner shown in Fig. 2, or toward the center of' the tube. The Water as it pours over the edge of this partition and into the space F, which forms the discharge-leg of the Siphon, Will draw the air out of the upper end of the space, E and cause the water therein to rise until it ows over the top of the partition D. As soon as this happens a siphon is formed which unless broken will empty the water in the tank A down to the level of the inlet-opening e. As soon as the Water in the cup I falls to the level of the upper end of the tube B the ball H, which is floating therein, will be seated upon the upper end of the tube. The suction caused thereon by the action of the siphon will serve to hold the ball securely upon the seat, and thus form an air-tight joint. It willv be impossible for the ball II to be sucked into the tube any distance, as the partition G extends more than half-way across the tube and is only a short distance below the top of the tube. When the chain K2 is released, the cup will fall and gradually settle into the wat-er, being thereby placed in condition for being operated again.

It will be seen that with my device there is no valve placed between the water in the tank and the flushing-pipe L, which must be maintained tight in order to prevent leakage of the water. The only way in which the water can escape from the tankinto the flushing-pipe L is either through the inlet-opening c and over the top of the partition D or over the top ot' the tube B. As the water-level in the tank is normally maintained below both of these points, no leakage can possibly occur unless the Siphon is started in operation after the manner'described. As soon as the water is lowered to the level of the inlet-opening e air is admitted to the siphon, and the flow of water is thus stopped.

The lower extension B of the tube B is secured to the flushing-pipe L by means of a union L or any other suitable means.

Having thus'fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A cistern-valve for water-closets, comprising a Siphon-tube having its bend extending above the water-level of the cistern, said tube having an open-ended extension above the bend of the siphon and connected with the discharge-leg of the siphon, a ball-valve adapted to seat upon and close the end of said extension, and means for temporarily surrounding and immersing said extension in water, substantially as described.

2. A cistern-valve for water-closets, comprisin g a Siphon-tube having its bend extending above the water-level of the cistern, said tube having an upward open-ended extension connected with the-discharge-leg of the Siphon, a ball-valve adapted to seat upon and close the end of said extension, a cup surrounding and sliding upon the Siphon-tube, and having a water-inlet opening of small area, and means by which the cup may be raised to float the ball and flood the siphontube, substantially as described.

3. A cistern-valve for water-closets, comprising a tube connected with a flushing-pipe and extending upward within the cistern to above the water-level thereof, said tube having a central longitudinal partition connected at its lower end with one side of' the tube and forming the suction-leg of asiphon, the tube having an inlet-opening into the lower end of the said suction-leg and communicating with the cistern, a transverselyextending partition in the upper portion of the tube and covering the upper end of the suction-leg, a valve adapted to close the upper end of the tube, and means for temporarily flooding the upper end of the tube and thereby raising the valve, substantially as described.
